Description

OneAccess ONE400 — Modular Multi-Service Enterprise WAN Router

The OneAccess ONE400 is a modular enterprise router combining WAN access, LAN switching, and voice telephony in a single expandable platform. Features serial WAN connectivity supporting V.11/V.28/V.35/V.36, dual Ethernet ports, and rear-panel expansion slots for optional modules. Backed by a 12-month Reboot IT warranty.

Key Benefits

  • Modular Expandable Architecture: Multiple rear-panel expansion slots accept uplink modules, additional Ethernet switch modules, and voice interface cards — allowing the platform to grow with your network requirements.
  • Multi-Service Consolidation: Combines WAN routing, LAN switching, and voice telephony (PBX integration) into one device, reducing equipment footprint and simplifying network management in branch offices.
  • Serial WAN Flexibility: The serial WAN port supports V.11, V.28, V.35, and V.36 standards with automatic DTE/DCE detection, enabling connection to a wide range of leased line and legacy WAN equipment.
  • Dual Ethernet Ports: Separate 10BaseT and 100BaseT Ethernet ports (both auto-sensing) provide LAN segmentation capability for network isolation or dedicated management access.
  • Voice-Ready Platform: Optional voice modules enable PBX integration and telephony services, making the ONE400 suitable for branch offices consolidating voice and data infrastructure.
  • Reboot IT Quality Assurance: Thoroughly tested and verified by Reboot IT's specialist network technicians, with all interfaces, routing, and expansion slots confirmed functional.

Performance in Use

The ONE400 performs well in branch office environments where network consolidation reduces equipment, cabling, and management complexity. IT administrators can start with basic WAN routing and LAN switching, then add voice or additional Ethernet capacity through the modular slot system as the site grows — without replacing the core device.

For organisations with existing leased line or legacy WAN infrastructure, the ONE400's serial interface with automatic DTE/DCE detection simplifies installation. It handles standard routing protocols, NAT, basic firewall, DHCP, and DNS relay simultaneously — covering the essential services required for a functional branch network from a single chassis.

Note that the ONE400 requires an external power adapter which is not included with this unit. The device is best suited to organisations with existing compatible power infrastructure or who are able to source an appropriate adapter. This is important to factor into deployment planning before purchase.

Frequently Asked Questions

Is a power adapter included?

No power adapter is included. A compatible external power adapter must be sourced separately based on your specific ONE400 model power requirements. Please confirm adapter specifications before purchase.

What WAN connection types does it support?

The ONE400 supports serial WAN connectivity using V.11, V.28, V.35, and V.36 standards with automatic DTE/DCE detection. This covers leased lines and legacy telecommunications equipment commonly found in enterprise WAN environments.

What modules can be added?

The ONE400 accepts OneAccess-compatible uplink modules, additional Ethernet switch modules, and voice interface cards through its rear-panel expansion slots. Module compatibility should be verified with OneAccess specifications.

Does it support modern broadband internet connections?

The ONE400 uses serial WAN rather than Ethernet WAN, making it best suited for serial leased line connections rather than modern NBN or fibre broadband which use Ethernet handoff.

Can it integrate with an existing PBX system?

Yes — with optional voice interface modules, the ONE400 supports PBX integration and telephony services, enabling branch offices to consolidate voice and data on a single platform.

What warranty is included?

Every OneAccess ONE400 from Reboot IT includes a 12-month warranty covering all hardware components, interfaces, and expansion slot functionality.

All-in-one Solution for Home Office

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!

Fair tech for price

Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.

Works excellently as advertised.

The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
